Nighttime full closure of westbound I-80 at the 1st Avenue interchange (exit 242) in Johnson County begins on Monday, Nov. 20


DAVENPORT, Iowa – Nov. 17, 2023 – If you drive on westbound Interstate 80 in Johnson County you need to be aware of a construction project for the new I-80/1st Avenue interchange that could slow down your trip.

Construction crews will close the westbound I-80 at exit 242 nightly from 11 p.m. to 5 a.m. on the following nights:

  • Monday and Tuesday, Nov. 20 and 21
  • Monday through Thursday, Nov. 27, 28, 29 and 30
  • Sunday through Thursday, Dec. 3, 4, 5, 6, 7

Interstate 80 will not be closed during the Thanksgiving holiday.

While westbound I-80 is closed you will be detoured off I-80 at exit 242 and then follow a marked detour route to resume travel on westbound I-80 (see map).

Help keep everyone on the road safer. Drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, you should stay alert, allow ample space between vehicles, and wear seat belts.
